#### To Add or Remove Ports

You can define the number of ports for some types of probe changers.

1. Select the appropriate probe changer from the Active probe changer list on the Ports tab (Edit | Preferences | Probe Changer).

2. Change the value in the Number of ports box. (This box is unavailable if your probe changer does not allow you to change the number of ports.)

3. To immediately see the changes, select the Apply button.
